' To all whom it may concern:

Be it known that I, ENOCH P, Sravans, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hangers for Arch Bricks, of which the following is a specification.

This invention relates to furnace arches of that type in which arch-forming brick are supported by clips suspended from a beam or other overhead structure and fashioned to' enter. into supporting engagement with reentrant portions of the bricks.

One object of the invention is to providea construction of clip that will gri the brick indirectly through the medium 0 an interposed member or members .(hereinafter referred to as inserts) and therefore without direct embrace or impingement against the brick by the clip, which,in constructions heretofore employed has frequentl caused spalling of the gripped portion of t e brick. Another object 1s to adapt such a clip to sustain a series of bricks of materially great- .er aggregate dimension than that of the cli by making the inserts vsufliciently rigid an of-sufiicient longitudinal dimension to ada 1: them to develop bridging suspension of the group of bricks lying between two clips, or, sustam, by cantilever on either side of and embrace of a clip.

A further object is to provide details .of construction of the parts which enter into the organization of elements employed whereby the before-mentioned objects will be realized, with economy and efiiciency.

hIn the accompanying drawings in which t e i5' i1 ustrated- Figure 1 is an elevational view showin an arch sprung between two abutments an eyon the immediate having its constituent bricks sus nded by.

sprung between abutments 2 such, .for instance, as furnace walls, and 3 represents an' overhead beam adapted'to support the arch at suitable intervals through the. medium of hangers comprisin rods 4 and brick-engaging clips 5. To a apt the bricks 1 to base supported, it is common to make them with a neck 6 fashioned to develo shoulders, undercuts, or reentrant portions which may readily b'e'gripped by the clips.

to conform to the surfaces of the brick and jaws between which they lie. Inserts 12 are.

elongated in the longitudinal direction of the arch so that in addition to transmitting support from the cli 5 to a brick or bricks lmmedi'ately under ying the clip, said inserts extend beneath the shoulders of a plurality of bricks on either side of the clip, or pre erably bridge the space from one clip to another so as to su port the intermediate bricks, as shown in Flgure 1, each clip bridg- Inserts 12, being of approximatel concave or angular section, as shown in igure 3, develop substantial rigidity both vertically and horizontally and thus. become particuthe bricks in align-- oreover, these inserts larly adapted. to kee ment with the arch.

artake ofv the curvature of the arch and ave one flange or leg of the substantially angular or concave section lying approx1- mately in the plane of arching, thereby stiffening the vertical support, and the other flange or .leg of the section: presented in a direction which is made up largely of a horizontal component which not only. develops the support beneath the shoulder of the brick but greatly stifi'ens the insert against horizontal distortion under the heat of the furnace. v

The clip 5 may be made separable into two parts, as, for instance, by dividing through means of the bolt 10.

its. head 7 on-the line 7, and uniting said parts ing the opposed ends of two pairs ofclips.

between said clips and ,said reentrant portion.

K2.Inarc With the construction as shown, not only is the archefiiciently sustained by means of cheap and durable construction, but any section of an arch. is made readily removable, since it is merely necessar to shift a ch in the longitudinal direction of the are a distance suflicient to release one end of a pair of inserts 12, which normall lie within the clip, when the inserts can removed and any one or more of the bricks sustained thereby can be re laced, after which the inserts are replace and the clip is restored to its position to embrace the adjacent ends of the inserts, whereupon the archwill be ready for further use.

' I claim: v i

f 1. In'an arch construction, a clip adapted to sustain bricks through the medium ofreentrant portions of the bricks, and an insert interposed between a clip and a brick and extending to sustaining relation to bricks lyin beyond the'clip.

constructions, embracing clips fashioned to sustain a brick through .engagement with a reentrant portion. of the brick, and inserts adapted to be interposed conforming in section to the clip and'to the reentrant portion of the brick, and having' longitudinal dimensions which adapt them to extend beyond the clip into reentrant portions of adjacent bricks and thereby sustain the latter in the arch.

3. In an arch construction, the combination of bricks having 'reentrant portions through which, they are sustained, inserts conforming to the reentrant ortions of a series of bricks and thereby a apted to sue tain said bricks in alignment, and clips embracing and supporting said inserts.

' 4. In an arch constructionya series of bricks having sustaining'shoulders, a plu insert "bricks lying between the clips.

5, In a furnace archtconstruction, a clip, and an insert through which the clip is adapted to support thevw bricks; said insert partaking of the curvature of the arch and .extending beyond the clip in supporting relation to bricks adjacent thereto.

- 6. In a furnace arch construction, a clip, and an insert throu h which the clip is adapted to support t e bricks said insert partaking of the curvature of the arch and extending beyond the clip in supportin relation to brlcks adjacent thereto; and sai I being of approximately angular sec tion.' i

7.- In a furnace arch construction, a clip, and an insert through which the clip is adapted to support the bricks; said insert partaking of t e curvature of the arch and extending beyond the clip in supportin relation to bricks adjacent theretog-and sai insert being of approximately angular seotion with one legof its section resented approximately in the plane of arc ing.

8. In a furnace arch construction, a clip,

and an insert through whichthe clip is adapted to support the bricks; said insert partakingof the curvature of. the arch and extending beyond the clip in supportin relation to bricks adjacent thereto; and sai insert being of approximately angular section with one leg of its section presented approximately in the planeof arching, and I with the other leg of said section approximately horizontal.
